Boyfriend problems

Asked my boyfriend to hangout today and he said it’s his coworkers birthday today and that he was gonna hang with them today when it’s another GIRLS birthday but she’s prob turning 16 and hes 19 BUT #1 HES WITH THEM ALL WEEKEND INCLUDING YESTERDAY and FRIDAY!!! And #2 he hasnt seen me in a WEEK! Im so fed up and he said “im sorry” which i ignored And faded him. Now he’s talking to me like nothing happened! Im so annoyed! Should i be annoyed tho or am i j being an overprotective girlfriend that j wants to see her boyfriend after a week! I mean maybe he already said to his coworkers that he can go meet up with them but IDK anymore im so upset. Ive been crying for so long.
